Choose true or false for each statement regarding concave mirrors.
true false  If an object is placed 4.1 cm from a concave mirror with f = 4 cm, then its image will be enlarged and real.
true false  A concave mirror produces an enlarged real image when the object is placed just beyond its focal point (Region 2).
true false  If an object is placed 7.9 cm from a concave mirror with f = 4 cm, then its image will be enlarged and real.

Choose true or false for each statement regarding convex mirrors.
true false  If an object is placed 7.9 cm from a convex mirror with f = 4 cm, then its image will be reduced and real.
true false  A convex mirror produces a reduced real image when the object is placed far beyond its focal point (Region 1).
true false  If an object is placed 4.1 cm from a convex mirror with f = 4 cm, then its image will be reduced and real.

Choose true or false for each statement regarding the sign conventions for mirrors.
true false  Virtual images appear behind a mirror and have a positive value for the image distance.
true false  The magnification m is positive for inverted images.
true false  The magnification m is negative for upright images.

Solutions

Expert Solution

1) If an object is placed 4.1 cm from a concave mirror with f = 4 cm, then its image will be enlarged and real. (True)

Reason: The closer the object comes to the focal point (without passing it), the bigger the image will be and real also.

2) True.

3) If an object is placed 7.9 cm from a concave mirror with f = 4 cm, then its image will be real but not enlarge.

4) If an object is placed 7.9 cm from a convex mirror with f = 4 cm, then its image will be reduced and virtual.

5) A convex mirror produces a reduced virtual image when the object is placed far beyond its focal point

6) If an object is placed 4.1 cm from a convex mirror with f = 4 cm, then its image will be virtual.

7) Virtual images appear behind a mirror and have a positive value for the image distance (True)

8) The magnification m is positive for inverted images (False)

9) The magnification m is negative for upright images.(false)
